wall outlet.
2. Turn the power control dial from the OFF position to the LOW or HIGH setting and rotate the
thermostat control knob in clockwise to the HIGH THERMOSTAT position to turn ON the heater.
Note: During the initial use of the heater, you may notice a slight odour or smoking as the result of

smell and smoke will leave off.

maintained automatically.
4. To lower the temperature, rotate the knob counter-clockwise towards the LOW position. To
raise the temperature, rotate the thermostat control knob clockwise towards the HIGH position.
5. Turn the power control dial to the fan setting and turn the thermostat control knob fully in a
clockwise direction to operate the fan continuously.
